4,500 running watts: what can it power?

The DuroMax XP5500HX delivers 4,500 W continuously and up to 5,500 W for a few seconds to start motors on gasoline. On propane, the manufacturer rates it at 4,275 running watts (5,225 W starting), 5% less. It handles 14 of the 14 loads on our typical list one at a time; add up the running watts of everything you run together, plus the extra starting watts of the biggest motor.

Fuel tank and runtime

The fuel tank holds 4 gallons of gasoline. The manufacturer quotes 19 hours at a quarter load. At half load, it runs about 9 hr on a full tank. That is about 0.44 gallon per hour at half load, or 11 gallons for a full day of running, so plan your fuel storage for a multi-day outage. On propane, a standard 20 lb tank holds about 4.7 gallons of LP; propane does not go stale, which makes it the easiest fuel to stock.

69 dB(A): how loud is it?

The manufacturer rates the DuroMax XP5500HX at 69 dB(A), usually measured at 23 feet (7 m) and a light load. That is a typical open-frame level, comparable to a vacuum cleaner: fine for home backup at 20 feet, loud for a campground.

4

Outlets and home connection

Its panel offers 2 × 120 V household outlets (5-20R), L14-30R 30 A 120/240 V twist-lock, USB ports. The L14-30R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.

5

Starting, safety and warranty

It has electric push-button start, with a recoil cord as backup. A CO shutoff sensor stops the engine if carbon monoxide builds up around it; it does not replace distance (20 feet from the house) and CO alarms indoors. It is listed as EPA compliant; check California availability if you live there. The warranty runs 5 years (residential use).

Typical price $500–$800: good value per watt?

Relative to its running watts, the DuroMax XP5500HX scores 8.3/10 on value: a good result. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
